This Red River expedition was inspired by cotton speculators for their own purposes of greed. It was intended to enable them to get possession of the great stores of cotton that lay in Louisiana and Texas. The expedition consisted of the army under Banks—a political general of far better military capacity than most political generals had—and a fleet of gunboats under that noted fighter, Commodore David D. Porter. Banks's army was opposed by a much smaller force of Confederates under General Richard Taylor, who nevertheless defeated it in an irregular action and drove it into a confused retreat which must have ended in surrender but for the protection of Porter's gunboats. Banks retreated painfully along the margin of the tortuous stream, nowhere daring to quit the gunboats' support even in order to save weary miles of marching around the bends in the river.
This expedition was ordered before Grant took command of all the armies. It was one of the many foolish blunders with the results of which the great Federal commander had to reckon and wrestle when he came into his own. As the spring of 1864 approached something happened which was of more importance to the Federal cause than any battle could be, or the success of any campaign. Congress and the administration recognized Grant as the great leader that he was, and gave him that authority of command which alone he needed in order to make an end of the struggle. On the twenty-sixth of February a bill passed by Congress revived the grade of lieutenant general in the army. Grant was promptly nominated for that office, and confirmed in it by the Senate on the second day of March. On the third he was ordered to Washington, and on the ninth Mr. Lincoln delivered to him his commission as lieutenant general, with authority to direct the operations of all the Federal armies in whatever part of the country they might be stationed.
Oddly enough in thus bringing to the front and giving command to the only general who had shown adequate capacity to direct the war to a successful conclusion, the administration still retained as its adjutant general that conspicuously incapable person, General Halleck, who had done more than all other men and all other influences combined to interfere with Grant's work in the war, to prevent him from accomplishing the ends he sought in behalf of his country, and to fritter away the fruits of his victories after he had won them. The shade of Winfield Scott still held in mortmain its strange influence over the Washington authorities. And General Grant's personal memoirs—though they make no complaint of this absurdity—very clearly show, that in the gigantic combinations which he was now called upon to make, he was often seriously embarrassed by this continuance of an authority to interfere in many ways with his plans.
The advent of Grant to the command of all the armies in the field wrought a revolution instantly and conspicuously in the conduct of the war. He had no sympathy whatever with the "pepper box policy." From the very beginning he had clearly seen that the strength of the Southern Confederacy lay in the fighting capacity of its armies. He had clearly seen that the problems of this war were not mainly geographical—that the occupation of this, that or the other position was of small consequence, except in so far as it tended to weaken the tremendous fighting force of that "best infantry on earth" which was defending Richmond on the one hand, and threatening Washington on the other.
Now that he had come into supreme command it was his first thought so to organize and coördinate all the operations of all the armies as to make them tend to the accomplishment of one supreme purpose—namely, the breaking and crushing of the Confederate power of resistance. As that power of resistance was centered chiefly in the Army of Northern Virginia, and in the genius of Robert E. Lee, Grant's grand combinations were all directed toward the destruction of that army, and the baffling of that genius.
As has been said already Grant was preëminently a man of practical common sense, and to his mind military problems were like any others that present themselves to the human mind—that is to say, they were problems, to be solved by the use of the means at command in the most effective way that could be thought of. War was to him like any other business. He knew that the administration had at its command, in men, money and materials, resources immeasurably superior to those which the South could control. It was his purpose to avail himself of that superiority in every way possible. In all that involved considerations of humanity or courtesy he had the delicate sentiments of a tender-hearted and generous man. But in the conduct of war he did not permit sentiment for one moment to interfere with common sense.
The strategy with which he undertook to fight the war out to a finish was simple. His "objective" was always the army opposed to him, and not merely a geographical position. In all his orders to all his lieutenants he emphasized this incessantly. In order to end the war he must crush the Confederate armies, and to that effect he instructed Sherman and every other commander under his orders.
Grant established his headquarters in Virginia in order that he might give personal direction to the operations of the Army of the Potomac. He did this with a most delicate consideration for Meade, who had direct command of the Army of the Potomac, and whose devotion and capacity he trusted implicitly, as he has himself testified in his memoirs.
It was his simple plan of campaign first to prevent Lee's reinforcement from any quarter, and secondly to hurl all the force he could concentrate against the Army of Northern Virginia for the purpose of destroying the resisting power of that army. In his judgment it was more important to cripple Lee than to capture Richmond. And in his judgment, also, to cripple Lee was to make the capture of Richmond easy and certain.
In order that Lee might not be reinforced, Grant began by issuing orders for vigorous operations in every other part of the Confederacy. He ordered Banks to withdraw from his wasteful cotton-seeking expedition up the Red river, to return to New Orleans, and to move thence against Mobile. He ordered Sherman to press back the Confederates in northern Georgia toward Atlanta, directing him to seize that town, and push on to the Gulf, thus again cutting in twain what remained of the Confederacy.
